A strong piece of evidence is the DNA report which confirms the involvement of all the five accused. Officials from Forensic Sciences Laboratories at Mumbai, Delhi and Ahmedabad are soon expected to send their reports to the investigators.

While the Mumbai and Delhi teams focused on samples from the crime scene, the Ahmedabad forensic team recorded voice samples of the accused.

Maharashtra government is keen to fast-track the case so that the culprits are given a harsh sentence at the earliest.
